    摘要： A fuel cell system and an operating method of the same. The fuel cell system includes a carbon monoxide adsorbing device that is disposed at an exit of a shift reactor and removes carbon monoxide which is not completely removed in the shift reactor. Therefore, a start-up time of the fuel cell system is remarkably reduced without poisoning catalysts of electrodes of the fuel cell. An overall volume of the fuel cell system can be reduced since the carbon monoxide adsorbing device is only operating during the start-up, and thus the fuel cell system can be economically manufactured and operated. Additionally, the carbon monoxide adsorbent can be regenerated, thereby increasing economic efficiency of the fuel cell system.

    摘要： In a startup method for fuel cell systems, and more particularly, a startup method which makes the fuel cell systems rapidly reach a steady state operation by significantly decreasing the time taken to increase the temperature of the shift reactor catalyst, gas discharged from a burner that heats a reformer is supplied into the shift reactor. In the startup method of the fuel cell system, the fuel cell systems rapidly reach a steady state operation thereby significantly improving the utility of the fuel cell system. In addition, the fuel cell system is economical in that gases discharged from burners included in the fuel cell system and waste heat are used.

    摘要： A receiver includes a local signal generator, a power phase adjuster, and a frequency converter so as to perform frequency conversion on signals included in a plurality of radio frequency bands. The local signal generator supplies a plurality of local signals. The power phase adjuster adjusts local signals in terms of signal power or relative phases. The frequency converter performs frequency conversion on radio frequency bands by use of local signals adjusted with the power phase adjuster, thus sorting them in a desired frequency range.
